OUTBOARD MOTOR SAFETY IMPORTANT SAFETY INFORMATION The TOHATSU BFT75A and BFT90A outboard motors are designed for use with boats that have a suitable manufacturer s power recommendation. Other uses can result in injury to the operator or damage to the outboard motor and other property. Most injuries or property damage can be prevented if you follow all instructions in this manual and on the outboard motor. The most common hazards are discussed in this chapter, along with the best way to protect yourself and others. Operator Responsibility It is the operator s responsibility to provide the necessary safeguards to protect people and property. Know how to stop the engine quickly in case of emergency. Understand the use of all controls. Stop the engine immediately if anyone falls overboard, and do not run the engine while the boat is near anyone in the water. Always stop the engine if you must leave the controls for any reason. Attach the emergency stop switch lanyard securely to the operator. Always wear a PFD (Personal Flotation Device) while on the boat. Familiarize yourself with all laws and regulations relating to boating and the use of outboard motors. Be sure that anyone who operates the outboard motor receives proper instruction. Be sure the outboard motor is properly mounted on the boat. Do not remove the engine cover while the engine is running. 7
OUTBOARD MOTOR SAFETY Refuel With Care Gasoline is extremely flammable, and gasoline vapor can explode. Refuel outdoors, in a wellventilated area, with the engine stopped. Never smoke near gasoline, and keep other flames and sparks away. Refuel carefully to avoid spilling fuel. Avoid overfilling the fuel tank. After refueling, tighten the filler cap securely. If any fuel is spilled, make sure the area is dry before starting the engine. Carbon Monoxide Hazard Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing carbon monoxide can cause loss of consciousness and may lead to death. If you run the engine in an area that is confined, or even partly enclosed, the air you breathe could contain a dangerous amount of exhaust gas. Never run your outboard inside a garage or other enclosure. 8

ARE YOU READY TO GET UNDERWAY? Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Knowledge Read and understand this manual. Know what the controls do and how to operate them. Familiarize yourself with the outboard motor and its operation before you get underway. Know what to do in case of an emergency. Familiarize yourself with all laws and regulations relating to boating and the use of outboard motors. Safety Always wear a PFD (Personal Flotation Device) while on the boat. Attach the emergency stop switch clip securely to the operator or to the operator s PFD (Personal Flotation Device). IS YOUR OUTBOARD MOTOR READY TO GO? For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the outboard motor to check its condition. Be sure to take care of any problem you find, or have your authorized TOHATSU dealer correct it, before you operate the outboard motor. BEFORE OPERATION Improperly maintaining this outboard motor or failing to correct a problem before operation can cause a malfunction in which you could be seriously hurt or killed. Always perform a preoperation inspection before each operation, and correct any problem. Before beginning your pre-operation checks, be sure the ignition switch is in the OFF position. 43
BEFORE OPERATION Safety Inspection Before each use, look around and underneath the engine for signs of oil or gasoline leaks. If you are using the portable fuel tank (optional equipment), make sure it is in good condition and properly secured in the boat (p.46). Check that the fuel hose is undamaged and properly connected. Wipe up any spills before starting the engine. Check the stern bracket to be sure the outboard motor is securely installed. Check that all controls are operating properly. Replace any damaged parts. Check that all fasteners are in place and securely tightened. Check the emergency stop switch for proper operation. Start the engine (p.18, 22 or 25). Make sure the engine stops by pulling the emergency stop switch clip from the emergency stop switch (p.60). Maintenance Inspection Check the engine oil level (p.78). Running the engine with a low oil level can cause engine damage. Check to be sure the propeller is undamaged and the castle nut is secured with the cotter pin (p.99). Check that the anodes are securely attached to the stern bracket and the gear case (p.98) and are not excessively worn. The anodes help protect the outboard motor from corrosion. Make sure a tool kit and the emergency starter rope are onboard (p.73). Replace any missing items. Check the fuel level in the fuel tank (p.88).

SAFE OPERATING PRECAUTIONS To safely realize the full potential of this outboard motor, you need a complete understanding of its operation and a certain amount of practice with its controls. Before operating the outboard motor for the first time, please review the IMPORTANT SAFETY INFORMATION on page 7 and the chapter titled BEFORE OPERATION. For your safety, do not start or run the engine in a confined or partly enclosed area. Your engine s exhaust contains poisonous carbon monoxide, a colorless, odorless gas that can collect rapidly. Breathing carbon monoxide can cause loss of consciousness and may lead to death. BREAK-IN PROCEDURE Break-in period: 10 hours Proper break-in operation allows the moving parts to wear in smoothly for best performance and long service life. Avoid continuous operation at a steady speed. First 15 minutes: Run the engine at trolling speed. Use the minimum throttle opening necessary to operate the boat at a safe trolling speed. Next 45 minutes: Run the engine up to a maximum of 2,000 to 3,000 rpm, which is about 10% to 30% of maximum throttle opening. Operating at maximum 2,000 ~ 3,000 rpm should be limited to 50% of the 45 minutes. OPERATION Next 60 minutes: Run the engine up to a maximum of 4,000 to 5,000 rpm, which is about 50% to 80% of maximum throttle opening.
